Abstract
This note shows that the genetic algorithm proposed by Keskintürk and Er (Computational Statistics and Data Analysis 2007, 52, 53–67) usually provides similarly effective stratification to that of the random search algorithm proposed by Kozak (Statistics in Transition 2004, 6(5), 797–806), although in some situations it can be noticeably less effective. Despite this, it is suggested that quite likely genetic algorithms have potential to be a means of very efficient stratification, especially in complex stratification problems.
